To all whom it may concern:

Be it known that I, HENRY PRICE, a c1t1- zen of'the United States,residing-at New- Castle, in the county of Lawrence and State ofPennsylvania, have invented a new and of which the following is aspecification.

- The present invention discloses a mold of novel form, adapted tofashion in one piece, the bowl of a water-closet and the lower, tubularextension thereof.

One object ofthe present invention is to provide a Structure of thistype in which an opening exists in the bottom of the bowl, above thespoon, novel means being provided for closing the opening, after thespoon has been fashioned.

Another object of the inventionis to provide novel means for forming thespoon.

The invention aims, further, to provide novel means for forming and forassem bling with the spoon, elements which cooperate to form the endwalland the upper wall of the outlet for the bowl.

The invention aims, further, to provide a novel process for forming thespoon and for closing an opening in the bowl above the spoon.

'It is withinthe scope of the invention to present a novel processwhereby the end wall and the upper wall of the outlet for the bowl areassembled with the spoon.

The invention aims, further, to improve generally, and-to increase theutility of molds whereby .water closets are formed.

It is within the scope of the invention to improve generally, theprocess whereby the water closet is formed, and to improve theseveralsteps of such a process.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides-in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing fromthe spirit of theinvention.

' The bowl portion of the closet is fashioned 1n a pair of main moldsections denoted by the numeral 1 as shown in detail in Fig. 3. One ofthese sections 1 upon its inner face, is provided with openings 2,adapted to receive bosses 3 which outstand from the inner face of theother main mold section 1, the

parts'Q and 3 cooperating to prevent themain mold sections 1 fromsliding upon each other and from changing their relative positions Themain mold sections 1 are duplicates, and each section is provided withan upper recess 4: and a lower recess 5, there being a passage 6extended between the recesses 4 and 5. The line, at which the upperrecess ,4 merges into the passage 6 is indi- Surrounding the upper endof the recess 4: is an annular groove 8 and radial grooves 9 communicatewith the groove 8. At the back of each main mold section 1 is formed aradial groove 10 which is deeper than the grooves 9. A superficialrecess 11 opens into the groove 10 and co nmunicates with the annulargroove 8. The recesses 4 and the passages 6 are lined wit-h plasticmaterial, in a sufliciently stiff condition to be worked readily by thefingers or by a tool, this plastic material being indicated by thereference character 12 in Fig.$). The two mold sections 1 are thenbrought into abutting relation, the bosses 3 registering in the openings2. The plastic material 12 is then caused to coalesce, by pressure orotherwise, along the lines 14 which indicate the places of abutmentbetween the inner faces of the sections 1.

The operation above described serves to fashion the bowl 1S and itsdepending tubular extension, the front Wall of the bowl. being indicatedby the reference character 15 in Fig. 1 and the rear wall of the bowlbeing indicated by the reference character 16, the reference characters17 serving to indicate, in Fig. 2, the side walls of the completedstructure and the bowl being indicated generally by the referencecharacter 18. By the operation above described an opening 19 (referringto Fig. 9) will be left in the bottom of the bowl 18, the periphery ofthis opening being defined by the lines 7, will be understood best whenFig. 3 is examined.

The structure, as thus far completed, comprises the bowl 18 and itstubular, depending extensions, and the next step, ordinarily, is toapply the spoon which, in Fig. 1, is denoted by the reference character28. In carrying-out this step. in the process, there is employed a spoonmold, shown in Fig. 4 and denoted generally by the numeral 20. The spoonmold 20 comprises a pallet 21, secured to which is a base 22. This base22 is shaped to correspond with the base of the finished product, thebase of the finished product being shown in Fig. 8 and bcin g designatedby the reference character lipstanding from the base of the spoonforming mold 20 is a pedestal 21 which adapt ed to fit in the passage(3. The pedestal 21 at its upper end extends but part way across thepassage 6, in the direction of the longer dimension of the passage, inorder that an outlet may be provided at the front of the structure. aswill be understood readily from Fig. 1. The upper end face of thepedestal Q 1, indicated at 25, is concaved both longitudinally andtransversely.

A section of plastic material, indicated at 26 in Fig. 11, is placedupon the end face 25 of the pedestal 24 and is compacted to approximatethe curvature of the end face 25. The main mold sections 1 are thensuperposed upon the pallet 21, the base of the spoon-forming mold 20registering in the lower recess 5 and the pedestal 21 extending upwardlyinto a passage 6. By this operation, the material indicated at 26 andcarried by the end face 25 of the pedestal 24 will be positioned to formthe spoon 28, shown in Fig. 1, the pedestal 21- serving to compact thetubular portion of the water closet in the passage 6. The materialindicated at 26 is then compacted manually so as to cause the same tocoalesce with the depending tubular portion of the bowl. along the linesindicated at 27 in Fig. 10. By this operation, the spoon :28 is mountedin place,

one end of the spoon 28 being joined up with the rear wall 16 asindicated at 29 in Fig. 1. It is now necessary to complete the 'upperwall of the outlet 100, indicated at 38 in Fig. 1, and to complete theend wall 39 of the outlet, and to join these parts to the spoon 28 sothat siphon maybe completed.

,equipped at one end with a boss h erally by the numeral 30 and may, forconvenience, be denominated the siphon mold. The mold 30 comprises apallet 31, provided with a base 32. corresponding in outline to the base23 of the finished product as shown in Fig. 8. Secured to and upstandingfr m the base 32 is an L-shaped element 33 comprising a. bed)! 31 and anupstanding stem :35, one end of the body being rounded off as shown at36. A mass of plastic material which, in Fig. 11, is indicated by thenumeral ST, is placed upon the body 34; of the L and upon the stem 35 ofthe L and is compacted upon these elements, to conform to the desiredshape. The main mold sections 1 are then lifted off the spoon mold, theparts being positioned as shown in Fig. 10.

The main mold sections 1 are then placed upon the mold section 30, theparts appearing as shown in Fig. 11. By this operation, the mass ofmaterial 37 which is carried by the L 33 is thrust upwardly into thepassage 6 and unites with the spoon 28 to form the end wall. 39 of theoutlet and to form the upper wall 88 of the outlet, reference being hadto Fig. 1. A chamber -10 will he formed at the rear end of the wall 38,where the same joins the rear wall 16', this chamber e10 resulting fromthe fact that one end of the body l-l is curved or rounded as indicatedat 3K3. Furthermore, there will be formed an other chamber 11, definedby the wall 38,

the wall 39 and the spoon 538. During the halting operation, of course,the chambers l0 and 41 are punctured to permit the steam and heated airto escape, thereby avoiding a luu'sting of the structure. It now remainsto close the opening indicated at 19 in the bowl 18. In carrying outthis step, there is em 'iloyed a bowl closing mold shown in Fig. (3 anddesignated by. the reference character 12. The bowl closing member 42comprises a pallet el -hprovided with radial ribs 44: and with a capProjecting from the cap 45 is a rib -16, the edge of which is inclinedas indicated at 47, the rib 4:6 being A piece of plastic materialindicated at d9 is applied to and worked down upon the inclined end face47 of the rib -16. The bowl closing member 12 is then inverted and isplaced upon the main bowl sections 1, the ribs 44 registering in thegrooves 9 and the cap piece 45 registering in the groove 8. The plasticmaterial indicated at 49 is received in a rabbct 50 formed in the bowl18 around the periphery of the opening therein and is joined up with theconstituent material of the bowl, to form the bottom closure 51, one endof the closure, indicated at 52, being determined by the boss 18 and theother end ofthe closure being connected up with the 'wall 15, asindicated in Fig. l. The bowl closing member 12 is then removed, leavingthe material 49 in place to form the closure 51. The base indicated at23 and shown in 8 is inserted into the lower recess 5 of the main moldsections and a ring 53, shown in Fig. 7, is assembled with the upperedge of the bowl, the ring 53 havinga hinge lug 154 extending into therecess 11, the hinge lug 5 1 being provided with an inlet 55 registeringin the deep groove 10. The main mold sections 1 may then be removed and,the structure will appear as depicted in Fig. 1. The device is permittedto dry out and,

after a sufficient period of time has elapsed, is baked in the usualmanner.

Attention is directed to the fact that the water closet herein disclosedis a one piece structure from top' to bottom. Owing to the fact that theopening 19 is left in the bowl, and owing to the fact that this opening19 is not closeduntil the mold section 42 is applied, access may be hadreadily to the 25 interior of the water closet, for the purpose ofclosing joints and finishing up the structure.

Having, thus described, the invention, what is claimed is z 1. Theherein described processof fashioning a water-closet body, whichconsists in forming the bowl peripherally leaving an opening in thebottom of the bowl; mounting a spoon in place below the opening; andclosingthe opening.
